Ford GT350 Canadian Price

Cadillac sells the ATS-V from $61K USD and $66K CAD.
Fords sell the GT350 from $56K USD and $74K CAD.
Don't understand the huge gap Ford vs Cadillac.
So compared to the GT350, in the US it costs more to buy a base ATS-V by $5K and in Canada is cheaper to buy the base ATS-V by $8K.
